Church Campus Network Rebuild: From Consumer Gear to Reliable Infrastructure
A 500-person church was running their entire campus off a single consumer router and three unmanaged switches. Sunday services regularly saw Wi-Fi dropout during the sermon stream. Here's how we fixed it — without an enterprise budget.
VLAN Segmentation for a Nonprofit: Separating Staff, Guest & IoT Traffic
A local nonprofit had staff laptops, donor kiosks, smart TVs, and guest Wi-Fi all on the same flat network. One compromised device could reach everything. We fixed that.
The Firewall That Wasn't: What We Found in a Small Business Security Audit
They thought they had a firewall. They had a router with the default password and UPnP enabled. A quick audit turned into a full remediation project — and a much better night's sleep for the owner.
Dead Zone Eliminated: Designing Wi-Fi Coverage for a Multi-Room Office
Three access points in the wrong places, all on the same channel. We remapped the space, ran the cabling properly, and got full coverage — including the back conference room nobody could ever get signal in.
Building NetProbe: One Tool to Replace All the Tabs
Every field tech knows the routine — ping in one terminal, traceroute in another, browser tabs open for DNS lookup, WHOIS, and SSL cert checking, and a $500/year license for anything that does it all in one place. NetProbe started as a frustration and turned into a fully-featured network analysis utility built from the ground up in Python.
The core idea was simple: a single portable app covering the full OSI stack — ICMP ping with live RTT graphs, continuous MTR, threaded port scanning, ARP/L2 discovery, DNS with DoH comparison, SSL inspection, HTTP timing, WHOIS, packet capture, and bandwidth testing — without requiring a paid subscription or a dozen separate installs.
Built on Python with a Tkinter GUI, the real engineering challenges came in the details. Raw socket access for ICMP requires elevated privileges on both Windows and Linux, and getting that to degrade gracefully took work. Bundling iperf3 and the Cygwin runtime alongside Scapy and a native packet capture stack into a single self-contained .exe via PyInstaller meant wrestling with dependency trees and binary paths. The architecture ended up clean: a core/engine.py handling all network operations in a threaded, callback-based model, and a ui/ layer that stays completely decoupled from it.
The result ships as a ~27 MB standalone executable on Windows and a single binary on Linux — no Python install, no dependencies to chase. Free to download.
